SWING.

SPECIFICATION forming part of Letters Patent No. 663,495, dated December 11, 1900.

Application filed September 23, 1899. derial No. 731,414. (No model.)

To all whom it ntay concern:

Be it known that I, EUGENIO K. HAYES, a citizen of the United States, residing at Galva, in the county of Henry and State of Illinois, have invented a new and useful Improvement in Swings, of which the following is a specification.

My invention relates, primarily, to portable swings or swings which after being set up can be moved around or changed as to location Without the necessity of taking the swing down. Swings of this class should be strong and rigid to withstand the strain in use and they should also be compact and light in order to be readily and easily moved about.

The principal object of my invention is to construct a swing that will be strong, rigid, and durable and at the same time symmetrical and light, employing in the construction light material without sacrificing the strength and rigidity of the parts.

The invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the drawing illustrating my invention, the figure is an elevation in perspective, showing the swing set up.

In constructing my invention and applying the same to a swing I make the frame of a single standard or upright A. This standard or upright is constructed from a single piece of metal, preferably high-carbon steel rolled or otherwise formed into shape to have a body of a T shape in cross-section, having a central flange or rib and a lateral portion extending both sides of the rib, so that each side is a wing or flange. This single piece of material so formed is bent into a yoke or U shape, so as to present two side pieces or legs a and a cross-piece a at the top. The side pieces or legs have an outward or transverse spread at the bottom, given thereto to act as a transverse brace when in position.

A cross arm or piece I) is secured to each side or leg of the standard at the upper end by bolts, and extending downward from the ends of this cross arm or piece isa somewhat V-shaped arm or piece I), also bolted to the side piece or leg of the standard. These two arms or pieces form a supporting or carrying head B for the suspending-bars, platform, and seats of the swing, and this head by reason of the straight cross pieces or arms and the diagonally-bent cross pieces or arms has a construction which, with the manner of attaching the cross-pieces to the standard, takes the push and pull in swinging, so that the thrust and draw of the movement of the swing is received and borne by the head through the cross arms or pieces and the diagonal arms or pieces and transmitted in a straight line downward to be carried by the single standard or support and have the weight of the occupants and the movements of the swing uniformly and evenly borne, rendering it practicallyimpossible to have any end tipping of the swing with ordinary use.

An inclined brace-rod 0, one for each side of the diagonal arm 1), extends down and is bolted or otherwise secured to the outer ends of base sills or supports D, to which sills are also bolted or otherwise secured the lower ends of the standard or upright. The side pieces of the standard having a transverse inclination and the brace-rods 0 having a lateral incline make a construction and arrangement by which the single standard or upright is given a strong bracing against both lateral and transverse strain in use.

The suspension or swing bars E, two for each side of the swing, are mounted or suspended by eyes or hooks d on a cross rod or bar 0 at the outer end of the straight and diagonal cross-arms, which rod also serves to tie or hold the ends of the cross-arms together, so as to form in effect a single piece. The platform F, composed of side rails f and cross-pieces f, is pivotally secured to and between the lower ends of the suspension-bars by cross or pivot rods 6, and the width of the platform and the distance apart of the suspension-bars are such in relation to the transverse spread of the standard and brace-rods as to leave a clear space between the swing and the frame to prevent any liability of injury in the use of the swing.

The seats G, one for each side of the swing, are each formed with a seat portion g and a back 9, and the seat is pivotally supported between the swing-bars by pins or pivots i, entered into the rail of the seat portion. Each seat has a guard rail or arm on a swinging plate which extends back and is provided with a series of notches h to engage a as a whole can be tipped or inclined to any position desired, and when properly adjusted can be locked and held in position by engaging a notch with the pin.

The single standard or support A is very strong owing to its body having a T-shaped formation, as the central rib thereof strengthens and stilfens the standard or support. This single vertical standard, with its transverse spread at thebottom and havingahead at its upper portion secured thereto and braced by inclined rods attached to the same base-sills as the standard, makes a frame very symmetrical and light, but of great strength and rigidity. The head carrying and supporting the suspension or swing bars and formed of the straight cross-pieces and the diagonal cross-pieces, each bolted at the center to the standard or support, has great strength and rigidity and is a form of construction by which the strain and thrust in use is transferred to the central single standard and is carried thereby in a straight line.

It will thus be seen that by my construction the swing has a strong and rigid frame made of a single piece of material,with a supporting or carrying head which is best adapted to receive the strain and thrust. The

frame and head are made of light material,

braced and supported in all directions, so that the push and pull and the thrust and draw of the swing in use are carried equally and uniformly, and thus one part has no more strain thereon than another. The parts are fitted together before being sent out, and by thus fitting the parts they can be easily put together at the place for use without employment of skilled labor. All that is required to set up the swing is to bolt the standards to the base-sills and bolt the head arms or pieces in place at the upper end of the standard, then attach the inclined brace-rods, and then suspend the swing-bars from their rods and attach the platform and seats in place, which completes the swing as a whole ready for use.

The construction and arrangement, while more especially designed for portable swings, can be used for swings which are to be anchored or held in a fixed position, as with such swings the frame and the head will have the same strength and rigidity and transmit and distribute equally the push, pull, and strain in use.

What I regard as new, and desire to secure by Letters Patent, is

1. In a swing, the combination of a single central yoke or U-shaped frame or support made of light material bent to have a top or cross bar and side uprights or standards with the side uprights orstandardslaterally spread at the bottom forming lateral braces, a rod or brace extending downward with an outward inclination from the upperend of each upright or standard, a base or bottom having the lower ends of the uprights or standards and the braces secured thereto, horizontal side bars or arms centrally attached one to each upright or standard at the upper end and each bar or arm having its end projecting equidistant on both sides of the frame or support, diagonal sidebarsor arms centrally attached one to each upright or standard below the horizontal side bar or arm and each diagonal side bar or arm extending upward on both sides of its central attachment to the extreme end of the horizontal side bar or arm and' i'urnishinga brace for'th'e horizontal side bar or arm, and a cross rod for the pivotal attachment of the suspension or swingba'r's and connecting-the extreme ends of the horizontal and diagonal side bars or arms, substantially as described.

2. In a swing, the combination of a single central frame o'r'support having on each side an upright or standard united at the top by a cross piece or-bar formed with the uprights or standards, a side sill orrail for thelower end of each upright or standard, a horizontally-extended bar'at the upper end of each upright or standard with its ends equidistant from the upright or standard, a diagonal bar or a'rm'at the upper end of each upright or standard extending from its point of attachment to the upright or standard upwardly to the extreme end of the horizontal bar or arm, a brace extending downwardly and outwardly from each side of the diagonal har or arm and secured to the side sill orrail of the upright,

and a cross-bar forthe pivotal attachment of the suspension or sWingba-rs and also connecting and uniting the extreme ends of the horizontal and diagonal bars or'arms, substantially as described.

3. In a swing, the combination of a single upright or standard'for each side of the frame or support, a horizontally extending bar or arm at the upper end of each upright or'standard, a diagonally eXtending bar or arm, running upward from the standard or upright to the extreme end of the horizontal bar orarm, and a cross bar or rod between the ends of the arms orbars and connectingthe arms or bars at the extreme ends and forming with the arms or bars a head for the swing, whereby the thrust and strain in use will be unifornlly and evenly distributed, substantially as described.
